understands. A new study suggests this tiny brain region plays a much more significant role in our vision than previously thought.
And the superior colliculus has been diligently doing its duty for a long, long time, preserved through millions of years of evolution. While it's relatively large in fish and amphibians though, it's a small Researchers from the Netherlands Institute for Neuroscience wanted to dig deeper into how animals, including humans, can separate objects from their backgrounds., the superior colliculus seemed like it might also be involved. Together with the visual cortex, it receives direct sensory input from the eyes, so to examine its function further, the researchers set up experiments in mice.
Using eye tracking and recording electrical signals in the brain, the researchers also noticed increased activity inside the superior colliculus when the mice detected objects around them. This was observed for both simple and more complex visual tasks. "Our measurements also showed that information about the visual task is present in the superior colliculus, and that this information is less present the moment a mouse makes a mistake,"before they get too close, the ability to distinguish an object from its background is a vital part of the visual processing mechanism in the brain, and this is valuable new insight into how it works.
